I noticed that when i was rearranging my appearance menu (clicking and draggin the bars) they were not working as expected. When I clicked a bar to drag it, it appeared about 500 pixels above where my cursor was, and the dotted lines were not moving at all. I disabled this plugin (which was the last one i had installed) and everything went back to normal with the menu and it was fine.
Hopefully this is enough information for you to look into it...if not let me know and i can provide more detail as needed. I like this plugin for my woocommerce so i'm hoping this is an easy fix.
